1.struts2 初识

struts2 简单登陆

将表单输入登陆信息显示在第二个页面

1.copy struts2 jar包
commons-logging-1.0.4.jar
freemarker-2.3.8.jar
struts2-core-2.0.11.jar
xwork-2.0.4.jar
ognl-2.6.11.jar

2.修改Tomcat server.xml

<Context path="/struts2" docBase="E:\MyEclipse\struts2\WebRoot" reloadable="true" />

3.修改项目 部署配置文件web.xml

<filter>
    <filter-name>struts</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>

<filter-mapping>
    <filter-name>struts</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

3.新建class处理action

package org.test.struts.action;

public class ActionLogin {
    private String username;
    private String password;
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String execute() throws Exception{
        return "success";
    }
}

3.新建struts.xml
在WebRoot/WEB-INF/classes文件夹下

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <package name="struts" extends="struts-default">
        <action name="login" class="org.test.struts.action.ActionLogin" >
            <result name="success" >/result.jsp</result>
        </action>
    </package>
</struts>

4.建立login.jsp

    <form action="login.action" method="post">
        username:<input type="text" name="username" /><br>
        password:<input type="password" name="password" /><br>
        <input type="submit" value="submit" />
    </form>

5.建立result.jsp

    username:${request.username }
    password:${request.password }
